Mix/Stir the Print Material

Before pouring any NextDent print material in the resin tray, you must mix the material bottle according to the chart below. Before printing again with those materials, you must stir the material in the resin tray using the Resin Mixer. Stirring the material in the resin tray serves two purposes: 1. Ensuring a good material mixture; and, 2. Ensuring there is not debris in the resin tray, such as partially cured particulates.

Resin Stirring and Curing Chart

CAUTION: Failure to sufficiently mix print materials according to this chart may result in color deviation and/or print failure.

 

The chart below serves as a quick reference for material-bottle mixing time on the NextDent LC-3DMixer, bottle hand-mixing time, material stirring time when material is in the resin tray, and part-curing time in the LC-3DPrint Box. For hand-mixing, shake the bottle vigorously in an up and down motion.

For part-washing times, these are identical for all NextDent materials. The first part bath should be three minutes in an ultrasonic cleaner with >90% alcohol solvent. The solvent may have been used to clean other parts for this first bath. The second part bath should be two minutes in an ultrasonic cleaner with clean >90% alcohol solvent. The solvent may NOT have been used to clean other parts.

As for part-drying times, these can vary depending on your drying method. Please see the section Part Drying for more information.

*Pre-shaking by hand

For best printing results, most NextDent print materials require that you pre-shake the bottle by hand before placing it on the LC-3DMixer for the specified time. This is to ensure that sediment thoroughly mixes with the rest of the material.

**Considerations for material that has been sitting, unused, for over 1 month

If you have a material bottle like this, simply treat it like a new bottle and mix it for the time specified in the "Brand-new bottle" column in the above chart.

 

NOTE: Ensure that you place the build in your UV curing oven in the same orientation it was printed in, as if the bottom of the oven is the print platform.
